Searching and presenting matching row in grid
Good evening! I am hitting my head with the following: having a textfield and there writing a value, I submit the value, and I need to iterate over the rows of a grid and fetch the page and present the record. So the template is like this: t:include="premiumNumber,internalId" rowsPerPage="50" pagerPosition="literal:both" t:add="delete" t:encoder="formencoder" t:mixins="GetsourceMixin"> ... .. The entries is a HashSet or ArrayList. Is it possible to search row by row a grid and if I find the row, roll over the pages and mark the record in a proper way ? Has anyone ever had stack with this ? Regards Dimitri p.s. is there a simple example perhaps with custom griddatasource fetching from a hashset/list/hashtable which involve thousands of records ? - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Are you using streams and/or threads on your pages and are they properly closed, even in case of exceptions? I can't tell you how many memory leaks I've plugged over the years in thread and stream handling. Invariably, the errors are in your own code. See https://plumbr.eu/blog/memory-leaks/what-is-a-permgen-leak for possible causes for a permgen memory leak. Also, you are in luck because Tomcat 6 added some useful tools for detecting memory leaks (see http://wiki.apache.org/tomcat/MemoryLeakProtection, and Tomcat 7 and up is even able to recover from some of them). Take a heap dump of the stressed out system and load it in your VisualVM.

input form error causes div to clear left
I have a form made up of 4 divs, the top 2 lay side by side using float:left, the next 2 are clear left so they stack underneath. When a field in the top right div contains an error the whole div clears left distorting the whole form into 4 stacked divs. How do I stop tapestries errors from messing up my form layout? regards, John
Re: tapestry 4.1.6 and pergmen question
Kalle, Chris, thanks for your answers. Unfortunately the problem is not related to webapp reloading even restarting the Tomcat service leads to out of PermGen in a few days, PermGen itself is quite large and I already use UseConcMarkSweepGC. Down here you can read the java settings : -Djava.awt.headless=true -Dfile.encoding=ISO-8859-1 -Xms512m -Xmx2048m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/tomcat6 -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled The cause of the space consumption seems to be the presence of a lot of classes of this type org.apache.tapestry.enhance.ClassFactoryClassLoader It seems that the more request the application serves the more PermGen increases and that's led me to think that the page pool is never cleaned up or at least not well cleanedup.
